Title: Method for cutting single crystal
Inventor: KURASHIGE KAZUHISA
IPC: B28D7/02
Filed: 1994-03-30
Abstract: PURPOSE:To largely reduce the cracking of a silicate compound single crystal by converting liquid to be used for cooling to non-aqueous liquid. CONSTITUTION:When a bond of Si-O exists in a crystal lattice, the bond of the Si-O on a surface of a crystal is hydrogen-bonded to water when it is cut by using the water, thereby becoming easy to cut. Thus, in the process using the water, the crystal is easily cracked. Accordingly, if the water is not used to cut the crystal, the cracking is prevented. As this non-aqueous liquid, liquid containing no water such as oil, organic compound used widely as organic solvent, etc., is used. Occurrence of the cracking can be completely prevented under the conditions using the oil as refrigerant, thereby largely reducing occurrence rate of the cracking.
